Turnover of highly educated R&D professionals: The role of pre‐entry cognitive style,work values and career orientation

Retention of key R&D experts has been recognized as a critical managerial challenge for many technology‐based companies. In this study, we propose that turnover of highly educated professional workers is meaningfully related to individual characteristics such as cognitive style, work values and career orientation. We tested the hypotheses using data collected from a sample of 132 R&D professionals with PhD degrees in engineering or natural science in a Korean electronics firm. The time‐dependent risk of turnover was estimated by survival analysis using a proportional hazards regression model. The results showed that over the 7‐year period after their organizational entry, R&D professionals with high levels of intrinsic values and cosmopolitan orientation were more likely to leave the organization than were their counterparts with low levels of intrinsic values and cosmopolitan orientation. The hazard function showed that the positive effect of intrinsic work values on turnover was particularly salient in the third and fourth year of R&D professionals' organizational tenure. We found that the positive effect of cosmopolitan orientation on turnover increased over time, introducing a greater risk of turnover with increasing tenure. The present findings have practical implications for the retention of highly educated R&D professionals in a corporate setting.     

成瘾相关记忆的表观遗传学机制 ——药物成瘾研究的新视角

成瘾相关记忆长期性的脑机制一直是药物成瘾研究领域的难点与热点,该文简要介绍了成瘾记忆长期性分子机制的研究脉络,提示表观遗传学修饰可能是研究药物成瘾的新视角。成瘾药物可以调节染色体不同亚型组蛋白乙酰化水平,不同基因DNA的甲基化程度从而改变染色体的空间结构,进而调节基因的表达导致成瘾,特别是DNA甲基化改变的相对的稳定性可能是成瘾记忆长期存在的分子基础。记忆再巩固过程中学习记忆相关脑区的记忆促进基因与记忆抑制基因的表观遗传学改变可能是未来研究的新趋势

聋生听力状况与读写成绩及认知能力关系的实验研究

为了研究聋生听力状况与其读写成绩及认知能力的关系,本文以聋校中年级学生为对象,采用实验的方法进行研究.结果表明:从总体上讲,聋生的听力损失、补偿情况与其读写成绩及认知能力之间均不存在显著的正相关.聋生认知、读写能力的差异,并不能由其听力损失、听力补偿情况进行简单的回归预测.研究建议:聋校老师在对聋生进行教育的时候,不要带着偏见去看待中重度听力残疾的聋生,要采取有效方法,来提高他们的认知能力和读写成绩.     

An Introduction to Latent Class Growth Analysis and Growth Mixture Modeling

In recent years, there has been a growing interest among researchers in the use of latent class and growth mixture modeling techniques for applications in the social and psychological sciences, in part due to advances in and availability of computer software designed for this purpose (e.g., Mplus and SAS Proc Traj). Latent growth modeling approaches, such as latent class growth analysis (LCGA) and growth mixture modeling (GMM), have been increasingly recognized for their usefulness for identifying homogeneous subpopulations within the larger heterogeneous population and for the identification of meaningful groups or classes of individuals. The purpose of this paper is to provide an overview of LCGA and GMM, compare the different techniques of latent growth modeling, discuss current debates and issues, and provide readers with a practical guide for conducting LCGA and GMM using the Mplus software.     

大众传媒商业化下的青少年伦理道德教育探究

青少年的伦理道德是作为从稚童向成熟个体过渡的道德认知、价值观念、道德情探、人格成长的有机结合,由于其具有不稳定的动因和表象,极易因外部环境和社会意识变化,如大众传媒的商业化浪潮等,发生文化取向、审美取向和价值定位的偏移和异变.当下的青少年伦理道德教育应该对大众传媒商业化环境下的道德认知多元化、价值观念虚拟化、人格发展真空化等诸多表象进行积极探源,继而树立起"理性评价"、"脱敏防范"、"积极建设"等科学原则并付诸实践,寻求伦理道德教育的创新,促进青少年的伦理道德向积极方向顺利发展.     

用仪器找寻上帝

心理学和神经学研究人员通过对颞叶癫痫症病人的研究,发现大脑负责“自我感觉”、情感反应和自我记忆的颞叶区某些部位对宗教体验的产生有明显的影响。根据这一发现,设计出一台仪器,激发一种特定的磁场,诱发健康人脑部颞叶产生类似于癫痫发作的症状,被试者会体验到身体漂浮、变形,并出现宗教内容的幻觉。通过科技手段,上帝现身都可以模仿了,信徒们声称的亲眼见过上帝等宗教体验还可信吗？     

Capturing spatial attention with multisensory cues

We assessed the influence of multisensory interactions on the exogenous orienting of spatial attention by comparing the ability of auditory, tactile, and audiotactile exogenous cues to capture visuospatial attention under conditions of no perceptual load versus high perceptual load. In Experiment 1, participants discriminated the elevation of visual targets preceded by either unimodal or bimodal cues under conditions of either a high perceptual load (involving the monitoring of a rapidly presented central stream of visual letters for occasionally presented target digits) or no perceptual load (when the central stream was replaced by a fixation point). All of the cues captured spatial attention in the no-load condition, whereas only the bimodal cues captured visuospatial attention in the highload condition. In Experiment 2, we ruled out the possibility that the presentation of any changing stimulus at fixation (i.e., a passively monitored stream of letters) would eliminate exogenous orienting, which instead appears to be a consequence of high perceptual load conditions (Experiment 1). These results demonstrate that multisensory cues capture spatial attention more effectively than unimodal cues under conditions of concurrent perceptual load.
